I went for shopping at supermarket after working. I picked up some groceries that I wanted to buy and took them into a shopping basket, and went to a casher. Since the total amount of the price was $10.60, I handed in $11.50 by mistake because I misunderstood in calculation. I thought the change was $1.10 at that time, so stupid. Staff of the shop at the casher, definitely, was kind of confused of what I did. Then, a customer who stands behind me on the casher, surprisingly, gave 10 cents for me. How kind she was! I had not asked her though. I gave my thanks to her, and I received one dollar for the change.
